When Samsung first launched the Note 10.1, it had some really solid ideas, but didn't do so well with the implementation. Soon after, the company released the the Note II, which improved on how it handled a lot of things that seemed to miss the mark on the Note 10.1 - namely multi-window, which allows more than one application to be run side-by-side.

Good news, though - Sammy just released a video that highlights the upcoming Premium Suite features that will be part of the Jelly Bean update, and it looks like they made a pretty major overhaul to multi-window.
